Some People Have Curly Brown Hair Tightly Pulled Back
Some=People/Have, Curly=Brown/Hair, Tightly=Pulled/Back
Sin = p/h, cos = b/h, tan = p/b
It is the easiest way of keeping the formula in the mind.
N.B: Write it sin theta, cos theta, tan theta
RECIPROCAL OF MAIN FORMULAE
.......................
COSEC=H/P (reciprocal of SIN)
SEC=H/B (reciprocal of COS)
COT=B/P (reciprocal of TAN)
